The present invention relates to a motor control device. The motor control device comprises: a module unit which outputs power of a battery as a motor current applied to a steering motor based on an input control signal; an ADC output unit which outputs an ADC value including a sensing value and a first offset value of the motor current; an error determination unit which is set in advance and determines an error of a first memory in which a second offset value corresponding to the first offset value is stored; a rotation determination unit which determines whether a steering device rotates when the error of the first memory is determined; an offset input unit which inputs the ADC value as a third offset value when it is determined that the steering device does not rotate; and a control unit which outputs a control signal based on a first motor current value calculated by compensating the second offset value to the ADC value when it is determined that there is no error in the first memory and outputs a control signal based on a second motor current value calculated by compensating the third offset value to the ADC value when it is determined that there is an error in the first memory. The objective of the present invention is to provide a steering motor control technique capable of reducing steering disturbance which may be caused by a changed sensing value.
